A. Lange & Söhne presents LANGE 1 DAYMATIC, the first automatic watch from the best-selling LANGE 1 family. Equipped with a newly developed in-house self-winding movement, this timepiece features a distinct dial layout with a retrograde day-of-week indication that forms the perfect counterpoint to the outsize date display.
Since it premiered over 15 years ago, the LANGE 1 has been the unmistakable face of A. Lange & Söhne. With its off-centre dial arrangement and the patented outsize date display, it became the manufactory’s instantly recognisable design icon, ranking among the most commended wristwatches of all times.
Its popularity prompted the development of a complete LANGE 1 family composed of six highly distinctive models that share one common asset: a manually wound movement with a twin mainspring barrel for a power reserve of three days visualised by a progressive power-reserve indicator.
However, there was never a self-winding LANGE 1 watch. The manufactory now presents the self-winding LANGE 1 DAYMATIC with a retrograde day-of week display.
Endowed with a newly developed self-winding movement, it affords a totally novel perspective of the LANGE 1. In comparison with the manually wound LANGE 1, the dial of the LANGE 1 DAYMATIC is reflection-symmetric. On its face, the main dial with the hour and minute hands is now on the right side.
The patented outsize date was moved from its customary position at the top right to the top left. Beneath it, the useful retrograde day-of-week display creates balance, replacing the power-reserve indicator which a self-winding watch does not require. The date and day-of-week displays can be conveniently and separately advanced with two push pieces.
As was the case with the classic LANGE 1, the displays of the LANGE 1 DAYMATIC are harmoniously arranged on the solid-silver dial. For instance, the centre of the outsize date and the arbours of the day-of-week and seconds hands are on the same vertical axis. This is the baseline of an isosceles triangle whose tip lies exactly in the middle of the main dial.
The case of the LANGE 1 DAYMATIC watch has a stately diameter of 39.5 mm, one millimetre larger than the LANGE 1.
It houses the self-winding calibre L021.1 which was developed from the ground up. A heavy central rotor delicately embossed with the “A. Lange & Söhne” signature occupies the entire 31.6-millimetre diameter of the movement. The platinum centrifugal mass on the outer rim of the rotor ensures highly efficient winding of the mainspring. When fully wound, it offers a power reserve of 50 hours.
The movement features many other quality traits that are typical for Lange, including the hand-engraved balance cock, an indexless oscillation system based on a large balance wheel with eccentric poising weights as well as a balance spring developed and manufactured in-house. It beats at a rate of 21,600 semi-oscillations per hour. The seven screwed gold chatons secured with thermally blued screws.
The LANGE 1 DAYMATIC is available in yellow gold, pink gold and platinum versions.
